a386262bfd Add OpenROADM equipment config file
The config file has the following properties:

* Includes only OpenROADM EDFA types (ILA / booster / preamp) and sets
allowed_for_design to true for ILAs.

* Sets ROADM restrictions to OpenROADM booster and preamp.

* Adds an OpenROADM transceiver type_variety with mode parameters
following the MSA spec.

* Sets other parameters (power_dbm, padding, add_drop_osnr, etc.)
according to OpenROADM MSA spec.

Using this config file together with auto-design should result in an
"OpenROADM compliant" network. Specifically, compliant fiber input
power levels for 50 GHz spacing are obtained by setting power_dbm = 2
and padding = 11. For other spacings than 50 GHz, power_dbm should be
changed accordingly.

bf0e435542 Include ILA nodes when converting from xls to json
Fix GitHub issue #217

Currently, if a user specifies an ILA node in an xls file, including
city name and coordinates, but does not specify type of amplifier,
etc., in the Eqpt sheet, the ILA node is not preserved when converting
to json. This patch proposes to include all ILA nodes to prevent loss
of information.

0f73a8f810 equipment: make sure all OpenROADM EDFAs have "openroadm" in their names
This could be (potentially) annoying to those users who rely on the
default equipment library. However, it brings at least some order into
the current state -- which was rather disorganized.

fa834338ab Introduce OpenROADM preamp and booster models
The NF calculated by the preamp model is compliant with the MW-MW noise
mask in the OpenROADM MSA spec. The booster is noise-free, which is
modeled by setting the NF to zero (-inf in dB units). This is obviously
unphysical but it is the simplest way to model the total noise
contribution from a ROADM, including preamp and booster, that is
compliant with the the OpenROADM MSA.

This also introduces two new EDFA type varieties,
"openroadm_mw_mw_preamp" and "openroadm_mw_mw_booster" in the equipment
library. I would prefer to also change the names of the existing
"openroadm" type_def and "standard"/"low_noise" type_variety,
representing an OpenROADM inline-amplifier, for better consistency but
this probably needs to be discussed first.

3a72ce84d0 Reverse order of values in example amplifier config files
As identified in GitHub issue #390, the dgt values (as well as gain and
nf ripple values) in example config json files are listed in order of
increasing wavelength (decreasing frequency) while the code assumes
values listed in the opposite order. This patch reverses the order of
values in affected files so that they are consistent with existing use
in the code.

Also, the f_min value in the Juniper-BoosterHG.json file is updated to
match measurement data so that interpolation is performed correctly.

be5519455f Change example file meshTopologyExampleV2.json
Following the change of the corresponding xls file in 60b9256 we should
change also this json file for consistency and to avoid unnecessary
confusion.

093085fba8 adding a roadm sheet to handle per degree info in roadms
This part only targets conversion from an xls input topology file.
In order to define per degree power, the convert function needs to know
the booster final name.
However before this change, the booster name may not be known if there
is no defined amplifier in eqpt sheet at this stage.
In order to solve this ambiguity, the final name are defined in the convert
function provided that the direction is defined in eqpt sheet and
even if the amp type is not defined.

Then the per degrre target power is defined in a new roadm sheet using
the same direction naming as for Eqpt sheet.

8eb5980ca9 distribute example data along GNPy
I would like to create a package for distribution to PIP, and this seems
like the path of least resistance.

This is, apparently, the way for shippign arbitrary data with Python
[1]. I've at least tried to make it user-firendly via adding a simple
utility which just prints out whatever that data path is.
